Wide spectrum of chromosomal

aberrations in human fetuses
The relative proportions of the various trisomies
observed in fetuses after spontaneous
abortion differ. The most frequent is trisomy 16,
which accounts for about 5% of all autosomal
trisomies. Autosomal monosomies lead to
death of the embryo within the first days or
weeks.
